Japan's volleyball team test their volleyball robot

Mounted to a track, these new digital defense droids slide up and down to pre-set positions, allowing players to test out their spike shots against many different team formations.Known as the "block machine" these rapid robots can travel at speeds of up to 3.7 meters per second, easily outpacing human players. So far these training machines have been used successfully in several of training sessions for Japan's national woman's volleyball team.
